transmitters (in any combination).

1. Connect the power cord.

2. Set the transmitter’s power switch to the off position.
(Note: The transmitter’s power is automatically turned off if the

transmitter is set in the charger with its power switch on; in this
case, the transmitter will resume operation when it is removed
from the charger.)

3. Install the Ni-MH AA batteries in the transmitter, observing correct
polarity as marked inside the transmitter. For installation instructions,
see the 2000 Series installation & operation manual.

4. Insert the transmitter into the charger with transmitter charging
contacts facing toward the charger’s contact pins.

5. Power is supplied to the charging bay when the transmitter is set
into the unit; at this point the red indicator of each port lights.
(Note: If the red indicator does not light, poor contact may be

the cause; set the transmitter in the charger again.)

6. When the charge is completed, the red indicator is turned off.

(Note: Maximum charging time is about ten hours.)

7. The unit keeps charging with ultra-low current (maintenance charge)
until the transmitter is removed from the charger.
